				FabienAuthorUnsubmitted Done Inline Actions Hum, no ? The test check that we building for OSX (i.e. Darwin), and not cross compiling, so we are running on native OSX. Then if we fall into this case, the error messages states that it is only supported on Linux, because the only supported build hosts for now (and for some time I think) are OSX and Linux. One can argue that there is some support for windows but it is through WSL or cygwin/mingw which identify as being Linux. Further more if some other host platform is used, then the message remains valid: the tools are only tested valid on Linux. Fabien: Hum, no ? The test check that we building for OSX (i.e. Darwin), and not cross compiling, so we…
